[0070] In this solution, the state coefficient in the state monitoring module after the early warning is turned on is gradually fine-tuned by the state adjustment module, so as to reduce the load on the rectifier by fine-tuning the stable input voltage, output current and power factor, thereby facilitating the extension of the service life of the rectifier as much as possible, and further providing sufficient response time for the operator to replace and repair the rectifier after the early warning alarm is turned on;

[0072] In the state monitoring module, the state coefficient is obtained through the input voltage, output current and power factor of the rectifier, specifically:
[0073] Step 1: obtain the input voltage per second within ten minutes up to the current time, make a difference between the voltages of adjacent 1 seconds to obtain the voltage difference, arrange all the voltage differences in order from small to large, select the median, mode and average of all the voltage differences, sum the median, mode and average of the voltage differences to obtain a reference value, set a preset threshold value for the reference value, sum the reference value with the preset threshold value for the reference value to obtain a maximum reference value, make a difference between the reference value and the preset threshold value for the reference value to obtain a minimum reference value, respectively record the number of voltage differences higher than the maximum reference value and the number of voltage differences lower than the minimum reference value in all the voltage differences, sum the number of voltage differences higher than the maximum reference value and the number of voltage differences lower than the minimum reference value to obtain the voltage value;

[0080] In this embodiment, the difference in the rectifier input voltage is calculated to facilitate the determination of the stability of the rectifier input voltage, and then the load borne by the rectifier is estimated and predicted based on the stability of the input voltage. The current at the rectifier output end is compared with the rated output current to facilitate the estimation and prediction of the load borne by the rectifier when it outputs current. The low power factor of the rectifier is monitored, and the future state of the rectifier is estimated and predicted based on the characteristic that the reactive power of the low power factor will cause the inductance and capacitor of the rectifier to heat up quickly. Finally, the current state of the rectifier is comprehensively determined by combining the input voltage, output current and power factor inside the rectifier, so as to facilitate the subsequent prediction of the working state of the rectifier.
[0081] In the state monitoring module, a line graph is drawn through the state coefficient, and a state database is established through the state coefficient line graph, specifically:
[0082] Step 1: Get the state coefficient of each second within ten minutes up to the current time, and get the time corresponding to each state coefficient;
[0083] Step 2: Establish an XY axis two-dimensional coordinate system, where the Y axis ordinate represents the state coefficient and the X axis abscissa represents time. Mark the coordinate point of each state factor in the two-dimensional coordinate system, and connect all the coordinate points in order from left to right to obtain a state coefficient line chart.
[0084] Step 3: Establish a state database, include all state coefficient line graphs into the state database and mark the corresponding time range in each state coefficient line graph.
[0085] In this embodiment, by drawing a state coefficient line chart and establishing a state database, it is convenient to record the long-term working state of the rectifier, and then it is convenient for inspection personnel to conduct random inspections of the rectifier according to the rectifier state records in the state database, making the recorded data more intuitive.
[0086] In the stability monitoring module, the environmental values of the rectifier are obtained, specifically:
[0087] Step 1: Obtain the average humidity and temperature every day after the rectifier is installed;
[0088] Step 2: Set a humidity preset threshold, capture the number of items higher than the humidity preset threshold in the average humidity of all rectifiers and mark them as high humidity items, set a temperature preset threshold, capture the number of items higher than the temperature preset threshold in the average temperature of all rectifiers and mark them as high temperature items;
[0089] Step 3: Weighted sum of the number of high temperatures and the number of high humidity to obtain the environmental value.
[0090] In this embodiment, by combining the temperature and humidity of the working environment of the rectifier, it is convenient to estimate the state of the rectifier according to the working environment of the rectifier, thereby facilitating the subsequent prediction of the working state of the rectifier.

[0093] Step 2: Weight the installation time, total usage time and total load times and add them up to get the lifespan value.
[0094] In this embodiment, by combining the installation time, working time and total load times of the rectifier, it is convenient to estimate the state of the rectifier according to the usage of the rectifier, so as to facilitate the prediction of the subsequent working state of the rectifier.
[0095] In the rectifier early warning module, the prediction coefficient is obtained by the state coefficient and stability coefficient of the rectifier, specifically:
[0096] Step 1: Obtain the state coefficient for each second within ten minutes up to the current time, obtain the stability coefficient for the day, and obtain the risk coefficient for each second within ten minutes up to the current time through the state coefficient for each second within ten minutes up to the current time and the stability coefficient for the day;
[0097] Step 2: Arrange all risk coefficients in chronological order, make a difference between every two adjacent risk coefficients to obtain multiple risk coefficient difference values, then sum and average all risk coefficient difference values to obtain the mean of risk coefficient difference, and sum the risk coefficient at the current time with the mean of risk coefficient difference to obtain the prediction coefficient;
[0098] The calculation method of risk factor is as follows:
[0099] ,
[0100] Among them, Fx represents the risk coefficient, Zt represents the state coefficient, and Wd represents the stability coefficient. and are weights, , .
[0101] In this embodiment, the risk coefficient is obtained by combining the state coefficient and the stability coefficient, so that the damage risk of the rectifier is comprehensively judged by combining the internal and external influencing factors of the rectifier, and then the future state of the rectifier is predicted according to the change of the risk coefficient of the rectifier at each time to obtain the prediction coefficient, so that the future state of the rectifier is judged according to the prediction coefficient.
[0102] The prediction coefficient preset threshold is set in the rectifier early warning module. The prediction coefficient and the prediction coefficient preset threshold are used to determine whether to start the early warning alarm to remind the management personnel. Specifically:
[0103] Step 1: Obtain the prediction coefficient of the current time and set the preset threshold of the prediction coefficient;
[0104] Step 2: Compare the prediction coefficient of the current time with the preset threshold of the prediction coefficient. If the prediction coefficient of the current time is greater than the preset threshold of the prediction coefficient, an alarm is activated to remind the management personnel to repair and replace the rectifier. If the prediction coefficient of the current time is less than the preset threshold of the prediction coefficient, feedback is given to the management personnel that the current rectifier is working normally.
[0105] In this embodiment, the prediction result of the rectifier is used to determine whether to start an alarm to remind the management personnel to replace and repair the rectifier during the non-emergency working hours of the rectifier, thereby facilitating an early warning before the rectifier stops working, providing sufficient response time for the operator to replace and repair the rectifier.
[0106] State adjustment module, specifically:
[0107] Step 1: Get the early warning alarm opening status, set the status request cycle, set the adjustment cycle, and set the status coefficient single adjustment value;
[0108] Step 2: If the early warning alarm is in the off state, the early warning alarm on state is obtained again at a time interval of the state request cycle. If the early warning alarm is in the on state, the current state coefficient is obtained, and the voltage, current and power factor of the rectifier are adjusted successively based on the single adjustment value of the state coefficient and the adjustment cycle as the time interval.
[0109] In this embodiment, after the early warning is turned on, the state coefficient in the state monitoring module is gradually fine-tuned, so as to reduce the load on the rectifier by fine-tuning the stable input voltage, output current and power factor, thereby extending the service life of the rectifier as much as possible, and further providing the operator with sufficient response time to replace and repair the rectifier after the early warning alarm is turned on.
